Somebody wanted to set breakpoints in their C code by marking them with a comment (note “d” for “debugger”):

  //d

You can get a list of them with a single Awk line.

  awk -F'//d[[:space:]]*' 'NF > 1 {print FILENAME ":" FNR " " $2}' source/*.c

You can even create a GDB script, pretty easily.

(IMO, easier still to configure your editor to support breakpoints, but I’m not the one who chose to do it this way.)
